XQuery syntax error: unexpected token "$"

[Steven Traut <st...@bea.com>]

Hello all -- Anyone know why the execQuery method should choke on line  
1 of the following expression? Am I missing something about the $this  
variable?

                 "for $e in $this/xq:employees/xq:employee " +
                 "let $s := $e/xq:address/xq:state " +
                 "where $s = 'WA' " +
                 "return $e"

Saxon is on the classpath. Artifacts below.

Thanks,
Steve
